The Minneapolis police officers involved in the November 2015 fatal shooting of Jamar Clark did not violate department policies and will not face discipline, according to Minneapolis Police Chief Janee Harteau.

The Minnesota Bureau of Criminal Apprehension has turned over its investigation of the officer-involved fatal shooting of Philando Castile to the Ramsey County attorney's office for charging consideration.

St. Cloud police chief William Blair Anderson said an off-duty officer from another jurisdiction confronted and killed the suspect. He said the suspect — who was dressed in a private security uniform — reportedly asked at least one victim whether they were Muslim before assaulting them, and referred to Allah during the attacks.

A crime-fighting tool until now kept under wraps by the Hennepin County Sheriff's Office is drawing both praise as a critical asset in the hunt for bad guys, but also concern in an era of growing surveillance.

Hennepin County Attorney Mike Freeman said evidence confirms officers' account that Clark grabbed one officer's gun and was not handcuffed when he was shot. Activists said some witness accounts were discounted.

The secret government witness has been linked to the global trade in drugs, guns and assassinations. He was expected in federal court in St. Paul on Wednesday to testify against several alleged underlings.
